Hello, 04_video_dec_trt with yolov3

Hello,

It says “Converts the image from YUV to RGB format and saves it in a file”

The output of this sample program is known only as a txt file containing the bbox coordinate information.
Can I save it as an image?
I’m not sure what exactly the sentence underlined in red means.
Can you tell me the meaning of the sentence?

Thank you.
